The present paper describes the behavior of a vertical riser in waves, currents and which is excited by displacements at the riser top. Fundamental equations for riser behavior are described and the Ferrari&Bearman model  is applied to estimate hydrodynamic load for “in-line” and transverse directions of the riser. Solution for riser behavior is obtained in time domain, calculations are performed for deepwater field production scenario and discussions are addressed. The influence of variation of riser diameter and drag coefficient along its length, the presence of floaters and effect of petroleum fluid flowing in the riser are investigated. Moreover, effects of the upper and bottom end conditions of the riser on its behavior are also taken into account in the analysis.
